Some disconnected thoughts
1) The book Dilla Time makes a compelling case for J Dilla being the difference - developed in the last 1990s but - but his influence is now everywhere in the 2000s
The music could have been made before the mid 1990s but it would have sounded different.

2) Frank Ocean's Blonde is another interesting case. It was released in a different form as Endless for one day before Blonde was released, and was , I think I'm right in saying, available for one day on vinyl then only available to download. It makes very creative use of things like autotune, spoken intermissions, blends hip hop, soul, rock, sampling. It's maybe my favourite new record of the last decade or so
I'm always blown away by this track even though I've played it hundreds of times. I'm not sure it could have come from 1995 but feel free to make the case.
3) From another angle, I recall re-reading ( but can't for the life of me remember where) that innovations in how we consume music have replaced innovations in music . In this article the ipod was being praised as in the cycle from from - Elvis > Beatles . Summer of love > punk > rave / electronic.
The walkman and CD led to longer records that were, in content, more of the same, and often recycling of older records in new formats. The i pod made that even more so and moved away from the primacy of the album, Spotify etc have again transformed how we consume the same thing and to some extent how records and music are made.
So there are lots of records being made now that we consume in different ways to in 1999 but I'm not sure anything revolutionary has happened to the music itself - except perhaps Dilla's beats?. The changes have become about what is in the mainstream ( way more black, female and queer artists) rather than the music. I think there are digital production sounds that place records in the last 10 or so years - the sound of St Vincent's records would be an example - but maybe not the content of the music.
Maybe there'a similar point about the way the live experience works. Taylor Swift could not have done what she's done with the eras tour in the last century - but the music could have easily been made then. Ditto Coldplay at Glastonbury last week.
That said, if you dare to put radio 1 on, the music is very different to what you would have heard in 1990 - things have evolved but maybe not radically changed (or, being of a certain age, got better)?
